Hale, 310 E. 44th St., New York, NY. 10017 Filed Nov.2, 1966, Ser. No. 591,457 US. Cl. 132-112 4 Claims Int. Cl. A45d 25/08ABSTRACT OF THE DISCLOSURE This invention relates to hair dyeingapparatus and in particular, to wet combs and brushes for applyingdevelopers, dyes, tints, bleaches, wave-set solutions and the like tothe hair.

In touching up or dyeing new growth of hair after it has been firstbleached, it is necessary to section the hair by making a fine part fromthe brow to the back of the head and then deliver the dye in a fine linealong the part. Before the dye has had a chance to run, it must becarefully blended usually by a thin piece of cotton swab onto the newgrowth being extremely careful not to overlap the dye onto the oldgrowth which had been previously dyed.

In order to apply this dye along the hair part, it is preferred todeliver the liquid directly to the part with the applicator nearlytouching the skin as it exits. It has been found that hair brushbristles may serve to blend in the dye in the region of the new growthjust as well as a cotton swab formerly used for this purpose. It is aspecial feature of this invention to provide as a single device a brushhaving a thin line of blending tufts and a detachable rubber applicatormounted on the brush handle for thumb activation and adapted to applythe bleach and the dye directly to the part prior to blending by thesame device. It is thus seen that the dye applicator is an integralcomponent separate from the brush which may be replaced as it wears outwithout affecting the structure or operation of the applicator.

One object of the invention is to provide a new and improved hair dyeapplicator.

Another object of the invention is to provide a hair brush and dyeapplicator as separable components but capable on assembly of deliveringbleach and dye in discreet quantities to narrowly prescribed areas ofthe head and of blending the dye in the hair as desired.

Other objects and advantages of the invention may be appreciated onreading the following description of one copy thereof which is taken inconjunction with the acompanying drawings, in which:

FIG. 1 is a perspective view showing the brush and dye applicator asseparate units;

FIG. 2 is a perspective view showing the brush and dye applicatorassembled; and

FIG. 3 is a section taken on the line 33 of FIG. 2.

Referring to the drawings, the numeral 6 refers to a comb and brushhandle having upper com'b teeth 8 and lower dye blending brush tufts 10in one end thereof, the tufts being formed in segments each having acomparatively narrow cross-section as shown in FIG. 3.

The dye applicator 12 is formed as a single component attachable to thebrush by clips 14 which yieldingly clip to the comb and brush betweenthe teeth and the tufts, respectively. The applicator is provided with athumb operated bulb 14 filled through capped aperture 15 and 3,424,176Patented Jan. 28, 1969 a communicating extension member 16 integrallyjoined thereto. Depending from the underside of the member 16 andextending nearly the full length of the blending tufts 10 are bottomaperture nobs 18 which communicate with the member 16 and are adapted todeliver bleach or dye mixtures directly to the line of hair part. Theno'bs 18 are slightly biased in the direction of the blending tufts 10so that liquid can be applied between pairs of blending tufts directlyto the desired area of the scalp while at the same time the tufts arepositioned for the blending operation immediately after the desiredliquid has been applied.

In the dyeing operation, first the hair is bleached, using a solution ofammonium chloride and hydrogen peroxide which places the hair incondition to accept the subsequently applied dye. The hair is thenusually dried. The next step is to section the hair by forming a partusing the comb side of the device. Then the device 12 is employed toapply the dye mixture for a given distance along the part and then toblend the dye into the hair using the blending tufts 10. If thebeautician is dyeing new growth of hair in a touching up treatment, hemust be careful to first bleach and then blend the dye into the hairjust from the roots to the end of the new growth being careful not tooverlap into previously dyed regions which would cause an undesired andunsightly change of color or tint in these regions. The sectioning,bleaching and'blending steps are then continued until all of the newgrowth is dyed to the desired tint.

It may be appreciated that there is an advantage in deploying the softrubber nobs relatively close to the blending tufts so that minimum timeis lost between the liquid application and the blending which greatlyfacilitates the blending operation that is so critical to successfultreatment. The provision of the nobs adjacent the tufts, assures thatthe bleach and dye is applied precisely into the part which is anecessary step prior to the blending. Also, the handle and reservoirbulb are completely separable and relatively positionable componentspermitting the operator to maintain a firm grip on the instrument whiledeftly applying just the desired amount of bleach and dye using thumbpressure for this purpose. The applicator having these features thus isbelieved to afford distinct advantages over priorly known like devicessuch as are shown, for example, in Patent No. 3,147,757.

Various modifications of the invention may be effected by personsskilled in the art without departing from the scope and principlethereof as defined in the appended claims.

What is claimed is:

1. In combination a hair treatment device comprising a comb having ahandle at one end and a plurality of blending tufts of narrowcross-section depending from the other end thereof and a dye applicatorremovably mounted on said comb having means for delivering dye directlyto the scalp.

2. The combination as defined in claim 1 wherein said means comprisesoft rubberized nobs the delivery ends of which are substantiallyadjacent said blending tufts.

3. The combination as defined in claim 2 wherein said applicator isprovided with a thumb bulb for containing dye solution and being acomponent separate fnorn said comb, said bulb is positionable relativeto the handle thereof to permit convenient thumb engagement and pressureto be applied to said bulb independently of the pressure of the hand onsaid handle.
